Stereo Imager

Parameters

Independent stereo width per band — narrow the lows, widen the highs.

Controls and display

Surface (the stage): a top-down view from the listening position. Frequency runs outward in rings — sub nearest you, air at the rim — and each band is a wedge whose opening is its width: 45 degrees is untouched (1.00), straight ahead is mono, the full quarter is twice as wide. The grains inside a wedge are what that band actually measures, from its live correlation, so a band that measures wider than the width you asked for spills past the wedge edge in amber, and a band folding toward mono collapses onto the centre line. Put simply: the wedge is what you asked for, the grains are what you got.

Edits on the stage: drag a wedge edge to set that band's width, drag a labelled ring to move a crossover, double-click a wedge to put it back to 1.00.

The column on the right carries the three width knobs, each in a dial ringed by that band's live correlation — green while the band is mono-safe, amber as it drifts, red once it is out of phase — with its value, its name, and a MONO SAFE / PHASE lamp. Under them the LOW SPLIT and HIGH SPLIT cells: drag a cell sideways to move that crossover (60 pixels is an octave), double-click for the default. A split cell lights under the pointer like the ring on the stage that edits the same number does.

At the foot, the last 12 seconds of all three correlations, +1 at the top and −1 at the bottom — a momentary phase dip you would otherwise miss.

The dock box shows the same stage and the same five readouts at a smaller size.
